why does my chicken look...weird? Acts normal?

I have the sweetest little silkie, called lady. She's about a couple months old now. She acts perfectly normal and everything: eats, drinks, runs, sandbaths, you name it. But I do not know why she looks this way on her face. She is a vaulted skull, and I had just presumed it had developed weirdly in the egg.
She has one slightly, but noticibly bulging eye and one shrunken eye. I refused to cull it off as a chick. She has a twin sister, who has the same case with the eyes. She acts fine too.
